- This invention relates to exteriorly capping bottles and other objects and nature readily understood art in the light tion of the accompanying drawings t containers, and the of the invention will be by those skilled in the of the following descriphat illustrate What I now believe to be the preferred mechanical expression or embodiment of my invention from among other forms,

constructions and arrangements within the spirit and scope of my invent on.

An object of the 1nvention is to provide for exteriorly covering tles and paper or other containers like material secured by like material that is removable the mouths of hotby hood caps of {paper or bottle mouth either separately or with the cap.

lVith this and other objects in view, my

invention consists in certain novel features in construction, and in rangements as more combinations or a1- fully and particularly set forth and specified hereinafter.

Referring to the accompanying ings.:-

Fig. portion draw- 1 shows in side elevation the mouth of a container exteriorly capped in accordance with my invention.

Fig. 2 shows 1n side elevation the mouth portion of a container exteriorly ,capped in accordance with my and securing means under the exterior rim container. Fig. 3 is a terial hood cap ta ner mouth.

vertical section.

The hood cap is composed of suitable flexible paper or paper per se can board or the like, and e of the common construction now round on the market, having the annular depending skirt 1, usually circular top 1,

and the flat central that is usually imom the printed or otherwise provided with display advertising, reading or other intelligible indicia. These caps are preferably-drawn from flat paper sheets by the use of dies to produce the 'capswith the flexible annular skirts or flanges that flare or enlarge in diameter downwardly so that the caps can be nested for packing and shipment, and so that the caps can be quickly and easily applied to and over the container months with the cap skirts depending at the exteriors of said mouths surrounding and extending below the exterior rims or shoulders of the container mouths.

The caps are designed to fit down on the top edges of the container mouths and more or less snugly fit the outer surfaces of the portions of the container rims of greatest external diameters.

The caps may or may not be waterproofed,

waxed or otherwise treated, and-the annular cap skirts are usually unbroken or continuous, but, if so desired, can. be formed with spaced vertical or longitudinal slits to facilitate the contraction of the skirts to the bottle necks under the rims or shoulders, without the formation of pronounced ridges or corrugations.

Acco rding to my invention, these flexible hoods or exterior caps are secured on the container months by paper or like material bands or rings 2 surrounding the cap skirts and holding suchskirts tightly contracted to and agamst the container rims in such manner as to prevent accidental displacement and removal of the caps from the containers, yet permit ready removal of the cap and retainer or securing band when it is desired to open the container forremoval of its contents.

In'the example band is composed of a strong, more or less. flexible, paper cylinder that in length is apillustrated, the securing,

proximately equal to the length of the hood of the hood cap located on the container mouth, the skirt of said cap will be surrounded bytheband and. tightly compressed and contracted against the container rim-so that the cap skirt grips the rim against accidental cap removal.

1 The securing band is preferably composed I tightly wound on a mandrel to form a long paper cylinder, and by appropriate means, this long paper tube or cylinder is cut into lengths, each of the curing band The bands can be packed for storage or shipment, while .in cylindrical form, or can be contracted by bending at diametrically opposite points and folded flat for packing, and'expanded for slipping onto the caps on the container mouths.

If so desired, the securing bands'can be.

impregnated with or otherwise embody one or more suitable wax like substances rendering the bands stifl or more or less rigid at atmospheric temperatures and soft or pliable when heated.

Such bands, while heated, can be slipped exteriorly onto tainer'mouths, and the lower portions of the soft bands can then be contracted by a. suitable contracting head, to contract the cap skirts tightly against the container necks under the. exterior rims or shoulders of the container mouths ,(see Fig. 2) so that thehands which will then rapidly cool and become stiff and set, will serve to lock and seal the cap skirts to the containers under the rims thereof.

' Where the stifi' locking bands are thus employed, the bottle or container months will e sealed, and, if so desired, the usually employed inner milk caps or sealing disks need not be employed. Also, where such stifl bands are employed, the hood ca cannot be removed'and'reapplied without detection, inasmuch, as the hand must be torn, mutilated or so expanded as to be apparent to the e e, to permit removal of the hood cap. sually, the bands are of a color different from that of the hood caps, to dis lay a distinctive band of color around t 0 cap on the bottle or other container. I

It is evident that various departures, modifications and variations might be resorted to without departing from the spirit and scope of my invention and hence I do not wish to limit myself to-the exact disclosures hereof.

What I' claim is I L'A flexible pzifier material hood cap having a downwar y enlargmg flaring andimensions to form a se-- paper materia the hood caps located on c'onimum exterior diameter of .ment, said cylinder in, length approximating cap to contractthe flared which closely approximates the maximum exterior diameter of said rim enlargement,
